Abstract
The present study introduced an integrated method
for the production of biodiesel from microalgal oil.
Heterotrophic growth of Chlorella protothecoides
resulted in the accumulation of high lipid content
(55%) in cells. Large amount of microalgal oil was
efficiently extracted from these heterotrophic cells
by using n-hexane. Biodiesel comparable to
conventional diesel was obtained from heterotrophic
microalgal oil by acidic transesterification. The
best process combination was 100% catalyst quantity
(based on oil weight) with 56:1 molar ratio of
methanol to oil at temperature of 30 degree C, which
reduced product specific gravity from an initial
value of 0.912 to a final value of 0.8637 in about 4
h of reaction time. The results suggested that the
new process, which combined bioengineering and
transesterification, was a feasible and effective
method for the production of high quality biodiesel
from microalgal oil. |
